DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a work truck for civil engineering works used for burying water and sewer pipes and interior protection pipes for various cables in trenches dug in an open-air moat on a road or the like. It is.

[0002]

2. Description of the Related Art Conventionally, when water and sewage pipes, communication cable protection pipes, and the like are buried in a trench excavated in a road, a target object is hung by a crane truck arranged beside the trench and put into the trench. However, working with this crane truck is difficult to maneuver and requires skilled workers, and it is necessary to secure enough space to stop the crane truck stably,
Road construction occupies the driving lane and is a major cause of traffic congestion.

[0003]

SUMMARY OF THE INVENTION Accordingly, an object of the present invention is to reduce traffic congestion by minimizing the road occupancy rate when laying water and sewer pipes, and to quickly, easily and safely secure water and sewer pipes. It is an object of the present invention to provide a trolley for civil engineering work in which a vehicle can be buried in a trench to solve the above-mentioned conventional problems.

[0004]

In order to achieve the above object, the present invention takes the following technical measures. That is, in the truck for civil engineering work according to the present invention, the truck is mounted so as to run freely across the rails 7 laid on both sides of the open-pit trench B for burying water and sewer pipes, cable protection pipes, and the like. A bogie A to be placed, a pair of right and left bogie frames 1 and 1 each having traveling wheels 2... And a cross beam member 3 connecting the bogie frames to the front and rear of the bogie frames 1 and 1; 3; a chain block 4, 4 provided in the middle of the cross beam member 3; and a vertically movable stabilizing foot 5 provided at the front and rear ends of the bogie frames 1, 1, respectively. In this structure, the spacing members 6 are provided with spacing adjusting means 6 so that the spacing between the bogie frames 1 and 1 can be changed.

A plurality of holes 8 are provided in the cross beam member 3 at predetermined intervals in the transverse direction as spacing adjusting means 6 for adjusting the spacing between the left and right bogie frames 1, 1. It is preferable that the bolt 11 is inserted through a hole of the connecting plate 10 fixed to the upper end of the support column 9 of the bogie frame 1. Further, the chain block 4,
4 may have a structure that can be slid and fixed to the left and right with respect to the cross beam member 3.

[0006]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS The details of the present invention will be described below with reference to the accompanying drawings. In the figure, reference numeral A denotes a truck according to the present invention, and rails 7 laid on both sides of a groove B dug to bury water and sewer pipes, cable protection pipes, and the like.
7 and run.

The truck A includes a pair of right and left bogie frames 1 and 1 each having traveling wheels 2.
Support pillars 9 perpendicular to the front and rear portions of the bogie frames 1, 1 ...
Are fixed integrally. The right and left bogie frames 1 and 1 are connected to each other at the upper ends of the left and right support columns 9 and 9 by the horizontal beam members 3 and 3.

Further, chain blocks 4, 4 are provided between the cross beams 3, 3, and the respective bogie frames 1,
1 are provided at the front and rear ends, respectively, of a stabilizing footrest 5 that can move up and down. The stabilizing legs 5 contact the ground surface by rotating the handle 5a to lower the screw shaft 5b, so that the traveling wheels 2 rise up from the rail surface and can stably hold the cart A.

The horizontal beam members 3, 3 are provided with a distance adjusting means 6 so that the distance between the left and right bogie frames 1, 1 can be changed.
Is provided. In the embodiment shown in the drawings as an example of the gap adjusting means, a plurality of holes 8 are provided in the cross beam member 3 at predetermined intervals in the lateral direction, and the arbitrary holes are provided with supporting columns 9 of the bogie frame 1. A bolt 11 is detachably inserted from a hole of a connecting plate 10 fixed to an upper end of the connecting member, but a double structure in which other means, for example, cross members 3 and 3 are slidably combined with a channel material. It is also possible to adjust the length by forming it.

The dimensions of each part of the bogie A are as follows: the length of the bogie frames 1 and 2 is 2 m, the reference value of the interval between the bogie frames 1 and 1 is 1.2 m, the span of the front and rear support columns 9 is 1.5 m, The height from the contact surface of the wheel 2 to the cross beam member 3 is 2.0 m
However, the dimensions are merely examples, and may be changed depending on conditions such as the work site, the size of the pipe to be buried, and the unit length.

The rails 7, 7 are arranged on both sides of the dug groove B. The rear portions of the rails 7 and 7 have already been buried with the water and water pipes and extended to the portion where the groove is filled, and the water pipe to be buried next is placed on the filled portion. Then, the truck A is moved to suspend the water pipe with the chain blocks 4, 4, and moved forward to stabilize the truck A with the footrest stabilizing feet 5, and then the chain blocks 4, 4 are lowered. The water pipe is lowered into the digging groove B. Each time the rails 7 and 7 are dug, a part whose construction is completed is added forward. In this way, the water pipes are sequentially embedded in the groove B. According to this method, the bogie A moves linearly along the groove, so that the conventional crane on the side of the groove is used. The work space can be reduced by eliminating the vehicle occupation, and congestion during road construction can be reduced. In addition, the work can be easily and safely performed even by a non-skilled person such as a manipulator of a crane truck.

In the cart of the present invention, as shown in the drawing, bar-side receiving members 12 having different heights are provided at both ends of the upper surface of the cross beams 3, 3, and the bar-side bars 13, 13 are provided thereon. By holding and holding the waterproof sheet 14 on the rods 13, 13 having different heights on the left and right sides, the rod 13 serves as a waterproof tent for working in a groove in rainy weather. At this time, the left and right rod holders 12, 1
Since the upper surface of the waterproof sheet can be held in an inclined posture by the difference in height of 2, the rainwater can be smoothly prevented from flowing downward and collecting on the top surface.

Further, in the present invention, since the bogie A moves linearly across the groove, the crane truck does not occupy a large space beside the groove as in the prior art, and the work area is reduced. It is possible to reduce the traffic, thereby reducing traffic congestion of traveling vehicles during road construction. In addition, even if the operator is not a skilled operator like a crane truck operator, the operation can be performed easily, safely, and quickly, which contributes to shortening the construction period and safety of the operator.

Although the representative embodiment of the present invention has been described above, the present invention is not necessarily limited to the above embodiment. For example, the chain block 4,
4 may have a structure that can be slid and fixed to the left and right with respect to the cross beam member 3. In addition, in the present invention, it is needless to say that the present invention can be carried out by appropriately changing the configuration within the scope of providing the components and having the effect.

[0015]

As described above, in the present invention, since the bogie moves linearly across the groove, the crane truck may occupy a large space beside the groove as in the prior art. As a result, the work area can be reduced, and congestion of traveling vehicles during road construction can be reduced. In addition, even if the operator is not a skilled operator like a crane truck operator, the operation can be performed easily, safely, and quickly, which contributes to shortening the construction period and safety of the operator. Further, in the bogie of the present invention, since the interval between the left and right frames can be adjusted, it can be applied to a single bogie with respect to the groove width which is changed depending on the size of the pipe diameter of the buried water pipe or the like. It has a remarkable effect of being economical.
